The raw materials of our company’s stainless steel products are all from well-known manufacturers, such as TISCO. Recently, the 304, 316, 1.4301, 1.4401 stainless steel hot-rolled and cold-rolled coils produced by TISCO in accordance with American and European standards have passed the PER certification of the British pressure equipment quality management system. After years of hard work and accumulation, various stainless steel, carbon steel, alloy steel billets, wire rods, medium plates, coils, and fine strips produced by TISCO in accordance with European standards, American standards, and Japanese standards have successively passed the pressure-bearing equipment of the European Union. Quality management system PED certification, best-selling overseas. After the UK leaves the EU, EU certification is no longer recognized, and access to the UK market must be certified by its designated agency. In order to further meet user requirements and expand overseas markets for stainless steel, the Manufacturing Department will lead relevant production plants and departments to actively promote PER certification. After preliminary planning, on-site research, data submission, on-site pre-examination, first audit, test witness, problem rectification and other stages, the relevant products have successfully passed the PER certification and are qualified to export to the UK pressure equipment field. The annual supply...
This kind of large-caliber ultra-thin-wall stainless steel seamless pipe product is our company’s special product. Previously, customers searched for many factories, but they were unable to produce such specifications. The larger the diameter of the steel pipe, the thinner the thickness. During the production process, cold drawing fractures are prone to occur, causing the steel pipe to be scrapped, and the risk cost is higher. Our factory has been transformed into the production of thin-walled stainless steel seamless pipes since 2010. After exploration and trial production, the current production experience is mature, the product tolerance requirements, and the mechanical properties fully meet the corresponding standards of ASTM, ASME, GOST, JIS, EN, GB, mainly exported to Singapore and the Middle East and Europe and the United States. Product parameters: Product name: stainless steel seamless steel pipe Material: AISI 321 Process: cold drawn Standard: GOST 9941-81 Specifications: 630mm×5mm Manufacturer: SHAANXI JINYOU METAL TECHNOLOGY CO., LTD 1. Before each cold drawing of the steel pipe, the whole process of wall measurement is carried out to ensure that the thickness of the whole steel pipe is uniform and not eccentric 2. After the heat treatment of the steel pipe, the mouth is slightly deformed,...
If you want to test the surface quality of 904L stainless steel plate, you usually have to wait until the pickling process after heat treatment. The pickling process can improve the smoothness and uniformity of the surface of 904L stainless steel plate. If the surface is not cleaned well before heat treatment, the quality will not meet the standard, and it will not meet the standard after pickling. Therefore, in order to improve the surface quality of 904L stainless steel plate, surface cleaning must be carried out before or during heat treatment. When the surface oxide scale of 904L stainless steel plate has uneven thickness, the surface roughness of the base metal surface displayed on various parts of the surface is also different, and in the pickling process, the dissolution of the surface oxide scale and the base metal at the scale attachment site The degree of corrosion by acid is not the same, so there will be uneven surface of 904L stainless steel plate. Oil is relatively easy to adhere to the surface of 904L stainless steel plate. The thickness and composition of the oxide scale on the attached part and other parts are different, and it will also...
